CURRENT- oron.

Specification of Letters Patent.

Patented Aug. 26,1913.

Application filed December 21, 1912. Serial No. 738,006.

To all whom it may concern Be it known that I, ROY Mao DEMILL, a citizen of the United States, residing at Stevensville, in the county of Ravalli and State of Montana, have invented new and useful Improvements in Current-Motors,-of which the following is a specification.

The present invention is primarily designed to utilize natural forces for operat ing machinery or parts to be driven for any purpose, such as irrigating lands, driving dynamos for generating electro-motive force or for driving machinery generally.

Specifically considered the invention embodies a motor wheel to be driven either by air or water currents, a supporting framework for the motor wheel and novel and peculiar mountings for the frame-work to admit of desired adjustment of the motor wheel or for moving of the same into or out of an operative position.

The invention consists ofthe novel features, details of construction and combination of parts, which hereinafter will be more particularly set forth, illustrated in the accompanying drawings, and pointed out in the appended claims.

Referring to the drawings, forming a part of the specification, Figure 1 is a side View of a mechanism for transforming natural forces into available energy embodying the invention. Fig. 2 is a top plan view of the engine. Fig. 3 is a transverse section on the line aa-w of Fig. 2. Fig. 1 is a longitudinal section on the line y-g/ of Fig. 2, showing the parts on a larger scale. Fig. 5 is an enlarged sectional view of the outer portion of the supporting structure and hub of the motor wheel.

Corresponding and like parts are re-' ferred to in the following description, and indicated in all the views of the drawings, by the same reference characters.

The motor wheel is indicated generally at A and the supporting structure comprises a beam B and standards G. -The beam B embodies similar arms or members which are oppositely inclined from a central point and taper toward their extremities. Each arm or member of the beam comprises four bars 1 which are outwardly converged and are connected at intervals in their length by means of struts and braces. The inner ends of the bars 1 are bolted or otherwise secured to a center frame which embodies uprights 2 and connecting members 3. A boxing 1 is secured between two adjacent uprights and receives the inner end of a shaft 5. Plates 6 are attached to uprights upon opposite sides of the boxing 4 and each has a tubular extension 7 which forms a bearing for a shaft 8 and which in turn is mounted in one of the standards G. The tubular extenslon 7 may project from opposite sides of the plate 6 so as to present an extended bearing for the shaft 8, which latter has a pulley 9 at its outer end and a bevel gear 10 at its inner end, the latter meshing with a bevel gear 11 secured to the inner end of the shaft 5. Power may be taken from either one or .both of the pulleys 9 for operating the ma chine or part to be driven. A truss brace 12 is secured at its ends to the outer extremities of the beam B and is supported at a middle point by means of a standard 13. The truss brace 12 may consist of a cable, rod or chain. The beam B is mounted to tilt about a horizontal axis and to turn about a vertical axis. The standards C, which may be of any construction, are secured at their lower ends to one member 14 of a turn table, the companion member 15 being mounted upon a bed or foundation 16 of any construction. The two members 14; and 15 may be connected in any manner to prevent relative displacement and as shown a king bolt 17 is provided for such purpose. The turntable may be of any construction such as generally provided for heavy structures to insure a substantial and durable support. The bed 16 is usually constructed of ma sonry or concrete.

The motor wheel comprises a hub 18, spokes or arms 19 and blades 20, the latter being secured to the outer ends of the arms 19. The hub 18 is flanged at opposite ends to receive the inner ends of the arms 19 which are bolted thereto. A tube 21 is secured to the outer end of one arm or member of the beam B and receives the outer portion of the shaft 5 which projects a short distance beyond the outer end of the tube to receive an end portion of the. hub 18, which is keyed thereto. The hub 18 is mounted upon the end portion of the tube 21 projecting beyond the beam and its outer end is contracted to receive the projecting end of the shaft 5. It will be observed that the motor wheel is mounted upon the tube 21, whereas the outer end of the shaft 5 has a bearing within said tube. The bevel gear 11 is keyed to the inner end of the shaft 5 and meshes with the bevel gears 10.

WVhen the invention is adapted to transform the power of a flowing stream into available energy the mechanism is located upon the shore at any convenient point in such position as to admit of the motor wheel having its lower portion dipping into the running water so as to be operated thereby. The tilting of the beam 13 admits of raising or lowering the-motor wheel to cause the same to dip into the water to a greater or less extent. The arrangement also provides for lifting the motor wheel so as to clear the water when movement of the beam B about its vertical axis enables the motor wheel to be thrown to one side out of the way of the stream so as not to obstruct traific. The end of the beam opposite that provided with the motor wheel is adapted to be raised or lowered and to be secured in the adjusted position and for this purpose a chain 22 is provided and secured at its lower end to an anchor 23 embedded in the ground, a hook 24L fitted to the end of the beam being designed to engage a link of the chain 22. It is to be understood that the beam is practically counterbalanced so that but very little force is required to be exerted to effect a raising or a lowering of the motor wheel. The end of the beam provided with the motor wheel is somewhat heavier than the op posite end to admit of the motor wheel being held in operative position by gravitative action.

It is to be understood that the invention while shown adapted for converting the force of a flowing stream into available force a different form of motor wheel, such as commonly employed in windmills, may be utilized, thereby adapting the invention for transforming air currents into available energy for operating machinery of any kind.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and

that such changes may be made when desired as are within the scope of the claims appended hereto.

. vHaving thus described the invention what is claimed as new, is

1. In apparatus for transforming a force into available energy the combination of a beam, a tube supported in an end of the beam and projecting beyond the same, a shaft mounted in the tube and having an end projecting beyond the tube, and a motor wheel mounted upon the projecting end of the tube and secured to the projecting end of the shaft to rotate with the latter.

2. In combination standards, aframework having hollow trunnions mounted in said standards, shafts mounted within the hollow trunnions, pulleys secured to the outer ends of the shafts, gear Wheels fitted to the inner ends of said shafts, a beam projecting from the framework, a shaft mounted in said beam, a gear wheel secured to the inner end of the shaft and in mesh wit-h the before mentioned gear wheels, and a motor wheel secured to the outer end of said shaft.

3. In combination standards, a beam mounted on said standards at a point intermediate of its ends, a truss brace connected at its outer ends to the extremities of the beam, a motor wheel at one end of the beam,

a shaft carried by the beam and having the motor wheel attached to its outer end, a second shaft mounted upon the beams and standards, and a gear Wheel secured to said second shaft and receiving the power from the shaft connected with the motor wheel.

4. A mechanism for transforming a natural force into available energy, the same comprising a turntable, standards mounted upon the turntable, a beam mounted upon in presence of two witnesses.
